Method Detail

generateCacheKey

public java.lang.Object generateCacheKey(java.lang.Object id,
                                         CollectionPersister persister,
                                         SessionFactoryImplementor factory,
                                         java.lang.String tenantIdentifier)

Description copied from interface: CollectionRegionAccessStrategy

To create instances of CollectionCacheKey for this region, Hibernate will invoke this method exclusively so that generated implementations can generate optimised keys.

Specified by:

generateCacheKey in interface CollectionRegionAccessStrategy

Parameters:

id - the primary identifier of the Collection

persister - the persister for the type for which a key is being generated

factory - a reference to the current SessionFactory

tenantIdentifier - the tenant id, or null if multi-tenancy is not being used.

Returns:

a key which can be used to identify this collection on this same region

getCacheKeyId

public java.lang.Object getCacheKeyId(java.lang.Object cacheKey)

Description copied from interface: CollectionRegionAccessStrategy

Performs reverse operation to CollectionRegionAccessStrategy.generateCacheKey(Object, CollectionPersister, SessionFactoryImplementor, String)

Specified by:

getCacheKeyId in interface CollectionRegionAccessStrategy

Parameters:

cacheKey - key previously returned from CollectionRegionAccessStrategy.generateCacheKey(Object, CollectionPersister, SessionFactoryImplementor, String)

Returns:

original key passed to CollectionRegionAccessStrategy.generateCacheKey(Object, CollectionPersister, SessionFactoryImplementor, String)
